SM Entertainment label mates TVXQ’s Yunho and Super Junior’s Eunhyuk, Sungmin, and Shindong have reunited while in the army to put their dancing and vocal talents to use for the military!

On June 23, the Republic of Korea Army’s YouTube channel shared a music video created for new recruits entitled “The Homeland I Protect.” Rather than a traditional, stirring army song, this track is clearly going for a true K-Pop vibe, which this unofficial sub-unit of K-Pop veterans naturally pulls off flawlessly.

All four guys wear their uniforms in the music video as they perform, with a group of dancers to back them up. Check it out below!

The four stars all enlisted in 2015, with Shindong joining on March 24, Sungmin on March 31, Yunho on July 21, and Eunhyuk on October 13. Yunho’s fellow TVXQ member Changmin is also currently serving in the military, as well as Siwon and Donghae of Super Junior.
